16 Claims. (01. 22951) s This invention relates to a wrapper for perishable goods and the present application constitutes a continuation in part of my copending application, Serial No. 34,817, filed August 5th, 1935, for an improved cigar package, wherein the application of the invention insofar as it relates to use of the improved wrapper with a cigar was specifically'described and claimed.

The wrapper constituting the subject matter of this invention is intended as a wrapper for food products such as bread, cheese, butter, coffee, tea, Y also cigars and other perishable goods which are likely to deteriorate with age, become stale, or lose their strength, fragrance or original flavor if exposed to air or moisture, for an extended length of time as often occurs when perishable goods are placed in a show case, or for display upon a counter or shelf in a store, or in a cabinet or upon a shelf or the like in a home before being used.

This'improved wrapper is particularly adapted for use in wrapping perishable goods which are customarily inspected before being purchased and/or which are not all consumed or utilized at the same time after purchase.

One object of the invention is to provide a wrapper formed of transparent or translucent substantially air-proof and moisture-proof material, provision being made whereby portions of the wrapper will be weakened by scoring or perforating same for severing or tearing when itis desired to remove a portion of the contents of the package for use, leaving the remainder of the contents in wrapped condition.

Another object of the invention resides in providing improved identification means for the contents of the package consisting of printing or painting upon the outer surface of the wrapper and so locating the same upon the wrapper that it will cover the perforations or scoring by which the wrapper has been weakened, thus sealing and strengthening the material at the weakened portions to prevent admission of air therethrough and. casual tearing or severance of the wrapper.

Another object resides in constructing a package that will enable articles to be displayed and rality of individual packages of coffee, tea or the like or blocks of candy or other goods enclosed in a wrapper of the improved construction;

Fig. 4 is a sectional view taken transversely through Figure 3- along the line 4-4;

Fig.5 is a fragmentary perspective view show ing butter enclosed in one of the improved wrappers;

Fig. 6 is a top plan view of a package of cheese enclosed in a wrapper of the improved construction; and a Fig. 7 is a view partially in section and partially in side elevation showing a cigar wrapped in pers or packages constructed in accordance with my invention.

In Figures 1 and 2, there has been shown a loaf of bread I enclosed in a wrapper 2 of the improved construction. This loaf of bread may be either sliced or unsliced but has been shown sliced which. seems to be the popular method of producing bread at this date. The wrapper is formed of transparent or translucent material such as cellophane, waxed paper or any other material which is transparent, or translucent in order that the bread may be seen and protected against air and moisture. v

The sheet of wrapping material is wrapped about the loaf of bread and its end portions folded against ends of the loaf as shown at 3 where it is pasted or otherwise secured. Lines 4 of perforations or scoring are formed across the sheet of wrapping material and the distance between the lines of perforations corresponds to the usual thickness of slices of bread so that when a sliced loaf is wrapped, the lines of perfor-- ations or scoring will form weakened portions be- It is desired to reinforce the weakened portions I of the wrapper and'in order to do so there have been provided bands 5 formed of ink or paint or other coating material. These bands extend entirelyaboutthewrapper in bridging relation to the lines of perforations or scoring and when the ink or paint or other coating has set, the bands serve very effectively to prevent accidental or casual tearing of the wrapper along the lines of perforations. These bands also serve as a means for sealing the perforations and preventing air or moisture from seeping inwardly through the perforations The bands may also serve as identifying and advertising marks and often constitute the trade-mark of the baking company broken through when tearing ofi portions of the a wrapper. It will thus be seen that portions of the wrapper between the lines of perforations can be readily torn on. without undue interference by the bands 5. It is not necessary to tear off a portion of the wrapper every time a slice of bread is to be used. When a sufficient number of slices have been removed to make it difficult to reach the remainder of the bread in the wrapper, the end portion of the wrapper which is open after the first tearing operation, may be folded to form an air tight closure which will protect the bread remaining in the wrapper from exposure to air and moisture.

In Figures 3 and 4. an embodiment of the in- I ventionhas been disclosed wherein a plurality of individual packages 6 of coffee, tea, candy, chocolate or the like are wrapped in one of these improved type of wrappers. These individual packages of coffee and tea may be very'desirable as they are intended to make sufficient coffee or tea to fill a single cup. These packages are assembled in stacked formation and while two tiers have been shown, it is to be understood that any number may be provided and each tierhave as many packages as desired. After the packages have been assembled, the stock is wrapped in a wrapper 1 consisting of a sheet of preferably transparent or translucent material which is airproof and moisture-proof as previously set forth 46 and the contents of the individual packages will be preserved against damage by air or moisture.

Lines 8 of perforations or scoring are formed across the sheet of wrapping material longitudinally and transversely thereof and the lines of perforations are so located that they extend along margins of the individual packages.

face of the wrapper along the lines of perforations or scoring in covering and bridging relation thereto and serves to seal the perforations and also serves to reinforce the portions of the sheet of wrapping material which have been weakened by the perforations. Therefore, the contents of the packages 6 will be enclosed in an air and moisture proof wrapper I but when it is desired to use the contents of one of the packages 6 it may be grasped and the wrapper I torn along the lines of perforations until the desired package 6 or a number of these packages can be removed. The

remaining packages will be left in the wrapper where they will be protected from exposure.

In Figure 5, there has been shown a pat ll) of butter'which is enclosed in a wrapper I I of transparent air-proof and moisture-proof material.

This sheet of wrapping material is folded about the butter and its'ends then folded against ends of the butter as shown at l2. Lines of scoring l3 extend across the wrapper in spaced relation to each other so that portions of the wrapper may be easily torn off as previously described and -with the marked scores on the wrapper.

Paint,--' ink or other coating 9 is applied to the outer these weakened portions are covered with ink, paint or coated material l3 so that the perforationsor scoring will be sealed and accidental tearing of the wrapper prevented. The butter may be a single large loaf or piece,. or may be in 5 a number of smaller pieces each individually wrapped, and packed together so that the surfaces where adjacent pieces abut are in register When it is desired to use part of the butter, it is merely 1 necessary to release the wrapper .at one end of the package and tear of! a portion of the wrapper according to the quantity of butter which is to be immediately used. The lines of perforations may also be used as a guide to cut the butter in indi- 15 ments l5 which form a complete circle when as- 20 sembled. The wrapper is formed of transparent or translucent air proof and moisture proof material and is scored with lines of perforations as shown at I6 so that portions of the wrapper and one or more cheese sectors bordered thereby may be easily detached while leaving the remainder of the wrapper intact. Bands l6 of paint or ink or other coating material are applied to the outer face of the wrapper along the lines of perforations and when the paint or ink or other coating has dried and set, the perforations will be tightly sealed and the portions of the wrapper weakened by the perforations reinforced. As previously explained the bands may serve as an identifying mark or other identifying or advertising may be applied with ink, paint or other ,coating with portions extending along or across the lines of perforations.

The protecting wrapper or package H shown in Figure 7 is also formed of a sheet of transparent air-proof and moisture-proof material having a line l8 of perforations intermediate its length. This sheet is either formed into a tube and the two cigars or cigar sections slipped into the tubular wrapper or the sheet may be wrapped about the cigars and its marginal edges then secured with one Overlapping the other. The end tabs 20 are then'folded over and secured to close ends of the tube and exclude air and moisture. Paint or ink is then applied to the outer face of the wrapper as shown at 2| to provide a simulation of a cigar band which serves as an identifying mark for the cigars in the wrapper and also as contact with portions of a cigar case or the lining 65 of a coat pocket.-
